We present exact numerical results for the friction force and the contactarea for a viscoelastic solid (rubber) in sliding contact with hard, randomlyrough substrates. The rough surfaces are self-affine fractal with roughnessover several decades in length scales. We calculate the contribution to thefriction from the pulsating deformations induced by the substrate asperities.We also calculate how the area of real contact, $A(v,p) $, depends on thesliding speed $v$ and on the nominal contact pressure $p$, and we show how thecontact area for any sliding speed can be obtained from a universal mastercurve $A(p)$. The numerical results are found to be in good agreement with thepredictions of an analytical contact mechanics theory.
